Ok, easy way - get a length of coat hanger wire and bend one end at
right angles and the other end at right angles in the opposite direction
- like a square 'Z'. i____ and file the end to a point.
l
Now put a flat plate ( maybe a piece of kitchen worktop would do if its
a constant thickness ) onto the table and mount one end of the wire in
the spindle. Bring the spindle down until the other end of the wire
almost touches the plate and rotate the spindle by hand watching the end
of the wire. If the axis is truly square to the table, the end of the
wire 'Z' should stay a constant height above the plate all round the
circle. This is the rough method but gives a good indication but, if the
circle swept by the wire is large enough, is really pretty accurate. An
alternative is to use a similar method but to substitute the wire 'Z'
for a rigid steel rod with the dial indicator mounted on the end of it -
this will give you some numbers to justify the effort you put into
clouting the axis with a hammer to set it true!! ;-). The degree of
accuracy of either of these methods depends upon the size of the circle
described by the rotation of the indicator on the plate and the flatness
of the plate.
